One-stage urethroplasty using a combination of buccal mucosa graft and Q penile skin flap for a complicated urethral stricture: A challenging case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
rationaleStrictures of the male urethra are common, often caused by trauma or occur idiopathically. The primary clinical symptoms include chronic obstructive voiding issues, and some patients may experience sexual dysfunction. Treatment choices mainly depend on the stricture's location and length. PATIENT CONCERNS: A 37-year-old man visited the urology department with lower urinary tract symptoms and recurrent urinary tract infections. He had a 5 cm urethral stricture previously treated with urethroplasty, which was unsuccessful. DIAGNOSES: A retrograde urethrography revealed the stricture, an extra-anatomical bypass, and a diverticulum.
interventionsA second urethroplasty was performed, using a combination of a buccal mucosa graft and a penile skin flap. OUTCOMES: Postoperative follow-up indicated improvement in the patient's voiding symptoms. A retrograde urethrography was done 3 months after the procedure showing a well-patent urethra with no complications. LESSONS: The key factors in deciding the treatment for urethral strictures are their location and length. Both grafts and flaps are effective for urethroplasties. However, complex long strictures with damaged urethral plates pose challenges for successful single-stage reconstruction. Combining a dorsal buccal mucosa graft to augment the urethral plate with a ventral onlay penile skin flap is a promising approach, leveraging the benefits of both tissue types. Combining grafts and flaps is advisable for reconstructing complicated urethral strictures with damaged urethral plates. Consulting a more experienced surgeon is recommended to minimize the risk of complications.
